I'm not sure how your body will react, but I can tell you what I would probably experience. I would probably have about 4lbs. water weight gain which would take about a week to go away, as long as I went back to induction level carbs and made sure I got my water in. I would also have to be careful that I really got back to Atkins in a committed way, just in case any cravings got started again. But, your body may have an entirely different response!
